you can expect and Philadelphia now in their fifth snowiest winter is where we pick up the story with Linzie Janis this morning. Good morning. Reporter: Good morning, ginger. We watched dozens of people sledding down these famous steps last night. This is what's left of one of those sleds. The steps now a giant sheet of ice. It has been a brutal and record-breaking winter for Philadelphia just like so many other cities. This morning, millions along the east coast crippled by ice and heaps of snow. The storm already responsible for at least 20 deaths. In New York City overnight, thunder sleet. This time-lapsed video shows the Manhattan skyline lighting up. A spirit airlines flight struck by lightning while it landed in Atlantic City. Heavy snow, the cause of at least four roofs collapsing in New York and New Jersey like this tennis center on long Island. In New Jersey, more damage at this residence in carnie and at a shopping center in Monroe and at this verizon center in Jersey City, three people treated for injuries after part of the roof caved in. In Philadelphia, the storm reaching historic proportions. This winter storm has now broken a 130-year record for the most six-inch-plus storms in a season. Reporter: Down south more misery. Roof of this Virginia gas station came crashing down. Cars stranded on the roads, completely buried. Only their mirrors visible. Now icy conditions are bringing down trees and power lines. Every time you hear something hit the roof you come out and run. Leaving 500,000 to brave the cold without power. Well, these storms have caused 14,000 cancellations, flight cancellations so far this week. That includes another 1,000 so far this morning.
